In the course of the corona pandemic, the demand for medical devices such as ventilators has skyrocketed. Air and gas flows as well as line and therapy pressures must be reliably monitored and controlled here. Among other things, this important work is carried out by the ultra-low pressure sensors of our customer, First Sensor AG. With the help of OurPlant micro-assembly systems from Häcker Automation GmbH, the piezoresistive pressure sensors can be produced automatically.
The sensors measure the lowest differential and relative pressures from 2.5 mbar full scale value. They have digital signal processing and guarantee very high levels of accuracy.
In ventilators, the highly precise sensors measure the smallest flows around the zero point of the respiratory flow and also detect flows of several hundred l / min. This mode of operation of the sensors requires absolutely precise and reliable production. With micro-assembly systems from Häcker Automation, First Sensor AG has a trustworthy partner for automated production at its side.
